do you need any special tools to install compression spring?
o.k., so I've ordered the stage 1 kit for my Buddy 50 and it comes with the yellow 1500rpm compression spring for the clutch. I have been reading how-tos and watching videos and some folks say you don't need any special tools, some folks say you do, and some folks beat on it with a hammer and screw driver Just wondering what folks here have used when they changed that spring. btw I do have tons of regular tools so thats not a problem and I just bought an impact wrench and sockets today. Just wondering if you need one of those clutch compressing tools or any other scooter specific tools.
also, I know the prima rollers don't last long but is there any other reason not to play with them for awhile? If not I figured I'd install them and when they wore out I'd replace them with the dr pulley weights.
Thanx

I just did this tonight. Pretty easy the second time.
Set the pulley on the ground and plate the spring and clutch on top. Sit on a chair in front of the pulley. Place both of your feet on the clutch and press down. You'll need to line up the notches, this might take a couple of attempts. When you press in on, use your hands to screw on the nut.
Be careful, the 1500 spring has a lot of potential energy.

I wouldn't use the C-clamps. There's too big a chance of them slipping once under compression. You'll poke your eye out... actually, you'll poke your face off.

yeah, definitely don't want to do that. I found a video on 49ccscooter.com that shows how to disassemble with a vice and reassemble by stepping on it. Looks fairly easy although I'm sure its only that easy the 100th time around.

my $ .02
Getting it off the first time is definitely a challenge. I used the strap wrench method that I saw online. I would say it's not as easy as everyone makes it out to be, if you're going ghetto like I did. (the strap wrench broke in the process)
But, like any shop project, if you have the right tools, it should make for a less stressful experience.
Do your research.
Once you loosen the screw, the rest is pretty easy.

I did take the clutch apart yesterday and replaced the spring. Your right, its not as easy as they make it look in the videos. That big thin nut is really on there tight. I had to use a strap wrench since my metal oil filter wrench was not large enough to fit around the clutch. It really tok an effort on my part but I finally got it off. I think it will probably be easier next time around. Thanks for everybodies input. It really makes it a lot easier to start playing around with the machine when you have a good community like this to help ya out

I was wondering what size the bolt was. nothing I had would fit so i had to use my vice and the strap wrench, what a pain in the arseNASRA wrote:A good investment is a 36mm socket and a electric impact gun if you plan on tinkering with your CVT. Makes life so much easier.
btw how do folks put the nut back on the variator and the clutch bell? Getting it off with the impact wrench was easy, but I had to try and hold it still with a strap wrench in one hand while I used the torque wrench with the other to get it back on, yet another pain in the arse.

wow, you can do that? Do you have some special tool that regulates torque on the imapct wrench or does the torque value just not matter that much on the variator and clutch bell nuts?NASRA wrote:Just hold the rear wheel and use the impact to install the nut.

I do it mostly on feel. I have my impact set to hammer at around 45ftpnds and I use a little blue locktight on each bolt I install including these. Never had a problem.jasondavis48108 wrote:wow, you can do that?

However you must be careful not to over torque the bolts as you can strip the treads out on the crankshaft and rear axle. Seen it done before and there is no easy fix for that issue.

Yikes! my impact gun cant be set for a particular torque guess I'll stick to the pain in the arse method for now.NASRA wrote:I do it mostly on feel.
